Equivalent & Substitute Parts for Würth Elektronik 860160272004

Part Overview

The Würth Elektronik 860160272004 is a 39 µF aluminum electrolytic capacitor rated at 10 V with radial through-hole mounting. This component is part of the WCAP-ATLL series and is designed for general-purpose applications requiring stable capacitance performance across an operating temperature range of -55°C to 105°C with a rated lifetime of 4000 hours at 105°C. The part is Active in product status and ROHS3 compliant.

Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage ratings, ripple current specifications, or impedance characteristics may vary to meet different circuit requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 860160272004 are qualified based on the following criteria:

• Capacitance Value: Must remain 39 µF
• Tolerance: Must remain ±20%
• Series: Must belong to WCAP-ATLL series
• Mounting Type: Must be Through Hole
• Package Configuration: Must be Radial, Can
• Physical Dimensions: Lead spacing, diameter, and height must match
• Polarization: Must be Polar
• Product Status: Must be Active
• Compliance: Must maintain ROHS3 compliance

Voltage rating may increase from the base 10 V specification to 16 V or 25 V, providing higher voltage margin for circuits operating below the substitute part's rated voltage. This substitution is valid when the circuit voltage requirement does not exceed the substitute part's voltage rating.

Parameter Comparison

Engineering Selection Recommendations

All three parts—860160272004, 860160372006, and 860160472006—are Active products with ROHS3 compliance and REACH Unaffected status. They share identical physical dimensions, lead spacing, and mounting configuration, ensuring direct mechanical compatibility on printed circuit boards.

The primary differentiation is voltage rating. The 860160272004 operates at 10 V, while the 860160372006 and 860160472006 provide 16 V and 25 V ratings respectively. Selection depends on the circuit's maximum operating voltage:

• Use 860160272004 for circuits with maximum voltage of 10 V
• Use 860160372006 for circuits with maximum voltage between 10 V and 16 V
• Use 860160472006 for circuits with maximum voltage between 16 V and 25 V

Higher voltage-rated substitutes provide increased safety margin and improved ripple current handling. The 25 V variant (860160472006) exhibits the lowest impedance at 1.5 Ohms, compared to 2.02 Ohms for the base 10 V part.

Frequently Asked Questions (FAQ)

Q: Can I use the 860160372006 (16 V) in place of the 860160272004 (10 V)?

A: Yes, provided the circuit voltage does not exceed 10 V. The 16 V rated part is mechanically and electrically compatible and will function correctly at lower voltages. The higher voltage rating provides additional safety margin.

Q: What is the difference between the three substitute parts?

A: All three parts maintain 39 µF capacitance and ±20% tolerance. The differences are voltage rating (10 V, 16 V, or 25 V), ripple current capacity, and impedance. Higher voltage ratings correlate with improved ripple current performance and lower impedance.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical lead spacing (0.079" / 2.00mm), diameter (0.197" / 5.00mm), and maximum seated height (0.492" / 12.50mm). They are direct mechanical substitutes on the PCB.

Q: Do all parts have the same lifetime rating?

A: Yes. All three parts are rated for 4000 hours at 105°C and operate across the same temperature range of -55°C to 105°C.

Q: Which part should I select for a new design?

A: Select based on your circuit's maximum operating voltage. If the voltage requirement is 10 V or below, any of the three parts is suitable. For circuits operating above 10 V, select the substitute with the next higher voltage rating to ensure adequate margin.
